The main aim of the project is to design and develop a touch screen interface to the ARM processor using the wireless technology, such that when the user touches the touch screen, the required graphical display will be displayed on the screen.





As shown in the block diagram above, the touch screen is connected to the touch screen controller, which has to be programmed to read the touch values in the real time environment. This touch data is then encoded and sent through the RF TX. At the other end the RF RX will be decoded and the same is then sent to the ARM processor, we will design the ARM kit and will not use the ready made ones. This is then connected to the graphical LCD. The ARM stores some predefined images, on the touch data received by the ARM, the assigned image will be displayed on the graphical LCD.
